Office hours and appointments for students
I do not schedule fixed office hours. If you need an appointment, please check my calendar and follow the suggestions on that page.
I'm currently involved in investigating high-speed packet processing (i.e., 10Gbps and beyond), while maintaining flexibility. We designed
several components that can be used to achieve this vision, from the
highly successful NetPDL language, the NetVM virtual machine, and their integration in the NetBee library. I also tried to apply these technologies to the problem of Traffic Classification, hence I spent some time on that topic too. With some very smart PhD student we had a look at the word of network processors and multicore/graphical CPU for networking; the first result is the iNFAnt pattern matching engine on nVidia graphics cards.
For several years I've explored the world of network processing, a.k.a. how to make the network programmable. This concept is now a buzzword named "Software Defined Networks", although it is so vague that you can do almost everything under that umbrella. In any case, over the year, I moved away from simple network programmability and I started thinking about moving services (whatever services) into the network. This is currently my main research activity, within a project called FROG (Flexible and pROGrammable network device).
My past research activities included Quality of Service in Packet Switched Networks, Scheduling Algorithms (particularly Class Based Queuing), Scheduling, Voice over IP, management of resources in peer-to-peer networks.

Some open source software projects I'm currently involved in:
- Universal Node: is a sort of “datacenter in a box”, hence providing functions similar to an OpenStack cluster, but limited to a single server.
- FROGv4: is an SDN/NFV/cloud service orchestrator that supports multiple heterogeneous domains.
- IOVisor-OVN: it extends the current Open Virtual Networking (OVN) project with a new backend based on the IOVisor technology.
Some open source software project I was involved in:
- WinPcap: a library for packet capture and network analysis for Windows
- WinDump: the porting of
the famous tcpdump tool
- Analyzer: graphical network sniffer for Windows
- WebLibrary: a
simple tool used to create online documentation, that can be easily printed (maintaining a good looking layout) and includes PowerPoint slides to be used in class.
- 46Bouncer: a simple
tool that accepts IPv4/IPv6 connections and translates them to IPv6/IPv4.
Useful to make IPv4 servers / applications available on the IPv6 domain
- GT: a tool for extracting ground truth from traffic traces, developed in in collaboration with University of Brescia (Italy)
- iNFAnt: an engine for Non-Deterministic Automata on nVidia GPUs
- Dyn@NG: a simple interface for virtualizing Cisco labs (through Dynamips)
- NetBee: the evolution of the WinPcap library; it offers a much more powerful object-based interface and it implements several modules (packet decoding, packet sniffing, ...) that can be used from external programs. Available for Windows and Linux.
